Abstract

Abstract. All organisms are ultimately dependent on a large diversity of consumptive and non-consumptive interactions established with other organisms, forming an intricate web of interdependencies. In 1992, when 1700 concerned scientists issued the first “World Scientists' Warning to Humanity”, our understanding of such interaction networks was still in its infancy. By simultaneously considering the species (nodes) and the links that glue them together into functional communities, the study of modern food webs – or more generally ecological networks – has brought us closer to a predictive community ecology. Scientists have now observed, manipulated, and modelled the assembly and the collapse of food webs under various global change stressors and identified common patterns. Most stressors, such as increasing temperature, biological invasions, biodiversity loss, habitat fragmentation, over-exploitation, have been shown to simplify food webs by concentrating energy flow along fewer pathways, threatening long-term community persistence. More worryingly, it has been shown that communities can abruptly change from highly diverse to simplified stable states with little or no warning. Altogether, evidence shows that apart from the challenge of tackling climate change and hampering the extinction of threatened species, we need urgent action to tackle large-scale biological change and specifically to protect food webs, as we are under the risk of pushing entire ecosystems outside their safe zones. At the same time, we need to gain a better understanding of the global-scale synergies and trade-offs between climate change and biological change. Here we highlight the most pressing challenges for the conservation of natural food webs and recent advances that might help us addressing such challenges.

科学家对濒危食物网发出警告
摘要所有生物最终都依赖于与其他生物建立的大量多样的消耗性和非消耗性相互作用,形成了一个复杂的相互依赖网络。1992年,1700年有关科学家发布了第一份“世界科学家对人类的警告”,当时我们对这种互动网络的理解还处于起步阶段。通过同时考虑物种(节点)和将它们粘合成功能群落的联系,对现代食物网——或者更普遍的生态网络——的研究使我们更接近可预测的群落生态学。科学家们现在已经观察、操纵和模拟了在各种全球变化压力下食物网的聚集和崩溃,并确定了共同的模式。大多数压力源,如温度升高、生物入侵、生物多样性丧失、栖息地破碎化、过度开发,已被证明通过将能量流集中在更少的途径来简化食物网,威胁到群落的长期持久性。更令人担忧的是,研究表明,群落可以在很少或没有警告的情况下,从高度多样化突然转变为简化的稳定状态。总之,有证据表明,除了应对气候变化和阻止受威胁物种灭绝的挑战外,我们还需要采取紧急行动,应对大规模的生物变化,特别是保护食物网,因为我们正面临着将整个生态系统推向安全区之外的风险。与此同时,我们需要更好地理解全球范围内气候变化和生物变化之间的协同效应和权衡。在这里,我们强调了自然食物网保护面临的最紧迫的挑战,以及可能帮助我们解决这些挑战的最新进展。

期刊介绍: Web Ecology (WE) is an open-access journal issued by the European Ecological Federation (EEF) representing the ecological societies within Europe and associated members. Its special value is to serve as a publication forum for national ecological societies that do not maintain their own society journal. Web Ecology publishes papers from all fields of ecology without any geographic restriction. It is a forum to communicate results of experimental, theoretical, and descriptive studies of general interest to an international audience. Original contributions, short communications, and reviews on ecological research on all kinds of organisms and ecosystems are welcome as well as papers that express emerging ideas and concepts with a sound scientific background.
